Abstract
A device includes a stationary structure, a spring and a proof mass. The stationary structure has a first portion and a second portion. The spring is over a substrate. The spring has a first protrusion protruded from an edge and extended toward the first portion of the stationary structure. The proof mass is over the substrate and supported by the sparing. The proof mass has a second protrusion protruded from an edge and extended toward the second portion of the stationary structure. A first gap between the first protrusion and the first portion is less than a second gap between the second protrusion and the second portion.
